Hi, Zoltan Kato,

As Jay and Frank already have recommended, I think increasing the
etimeout value is the way to go.

According to your posting you have 300 seconds for that right now ...
thatŽs 5 minutes. This is the default value and seems too low for your
situation. You have loads of files on that partition, so tar has lots
of work to do, as your former posting of the output of top shows.

The sendsize.debug files in your /tmp/amanda-directory (or whereever
your amanda-installation puts its logfiles ....) tell you about the
commands Amanda uses for estimating.

You can find those commands by looking for lines containing something
like

> getting size via gnutar for /home level 0

Some lines later there follows something like

>  argument list: /bin/tar ....

Run that command manually, maybe even using the time-command:

# time tar ...

This will run for a while, giving back the time it took. Set your
etimeout somewhat higher and try a run again.

---

Otherwise set it up to something like 3600 (one hour) and try that.

Another way would be to split the /home-directory into some smaller
disklist entries.

But more on that later if necessary.
